1存在问题安徽晋煤中能化工股份有限公司二期合成装置中,驱动氨冰机的汽轮机采用工业拖动汽轮机,其排汽缸为焊接汽缸,排汽缸与排汽接管需要在现场进行焊接。现场施工时,先将凝汽器、排汽接管就位,再就位汽轮机,在调整好汽轮机标高、水平及相对位置后,即可焊接排汽接管。开始施工时,先打磨处理焊口,调整好尺寸位置后,进行焊接。完成对称焊接后发现:排汽缸左侧支座翘起
1 Existing Problems In the phase II synthesis unit of Anhui Jinneng Zhongneng Chemical Co., Ltd., an industrial ammonia-powered turbine is driven by an industrial steam turbine. The discharge cylinder is a welding cylinder, and the discharge cylinder and the exhaust gas takeover need to be welded in the field. On-site construction, the first condenser and exhaust take over, and then place the steam turbine, adjust the steam turbine elevation, level and relative position, you can weld the exhaust manifold. Start construction, the first polished processing weld, adjust the size position, the welding. Finished symmetrical welding found: exhaust cylinder left tilt support
